Title: Wire feed control device for welding
Inventor: NISHIDA YORIAKI
IPC: B23K9/12
Filed: 1980-08-20
Abstract: PURPOSE: To make the life of relay contacts longer by transmitting a wire feed instruction signal to a thyristor gate circuit for controlling a wire feed motor after a constant time since a welding start signal.  
     CONSTITUTION: When relay contacts 3a, 3b are closed at the start of welding, the base current of a transistor 7 flows but on account of the time constants of a capacitor 9 and a resistance 8, the TR7 goes on by having a time lag from the relay contacts 3a, 3b. The instruction signal of a wire feed instruction signal circuit 6 is transmitted to the gate circuit 4 of a thyristor 2 for controlling a wire feed motor 1. This results in that the instruction signal is transmitted to the gate circuit 4 after the motor current circuit of the thyristor 2, the motor 1 and the relay contacts 3a is formed. Hence, a time difference is provided between the bouncing time at the closing of the relay and the conduction time of the motor start currnet and therefore the life of the relay contacts is made longer.

Inventor: TACHIBANA MANABU
IPC: G07F13/06
Filed: 1995-05-15
Abstract: PURPOSE: To improve the degree of mixture of sirup and a diluent water by starting discharging the sirup and specified time after the diluent water begins to be discharged, and stopping discharging the diluent water a specified time after its end. CONSTITUTION: The sirup begins to be discharged A seconds after the diluent water begins to be discharged and the discharging ends B seconds after the discharging of the sirup ended. Namely, the diluent water begins to be discharged to a cup, the sirup is discharged the specific time later, and the discharging of the diluent water is stopped the specified time after the discharging of the sirup ended, so that the sirup is mixed with the diluent water that is previously discharged. When the discharging of the diluent water is stopped before the discharging of the sirup ends, sirup discharged after the diluent water is stopped is not stirred in the cup and the sirup is left in the cup without being dissolved.  In this case, since the discharging of the diluent water acts to stir the liquid present in the cup, the discharging of the diluent water is stopped after the discharging of the sirup ended.

Title: Method of starting magnet type synchronous motor
Inventor: OKAJIMA IKUO
IPC: H02P1/46
Filed: 1978-09-22
Abstract: PURPOSE: To quickly trip the synchronization of a magnet-type synchronous motor by acceleraing it by applying initial voltage of high frequency thereto, lowering the generated frequency when accelerated to trip it in synchronous state, and then increasing the frequecy.  
     CONSTITUTION: Frequency f 0  is first applied from a variable frequency power supply 1 to a magnet-type synchronous motor 3 to initially start the motor. When this motor is accelerated to some degree, the generated frequency of the power supply 1 is lowered to the frequency f 1  lower than the frequecy fo capable of tripping synchronization at accelerated rotating speed thus accelerated at the initial operation to thereby trip it to synchronization. After this tripping operation of syncronization, the generated frequency of the power supply is raised to operating frequency as desired to thus complete starting of the motor. This method can trip the motor in synchronous state in short time and apply the low voltage to the motor at initial time. Accordingly, it can further reduce the starting current of the motor.

Title: Protecting film-forming agent of thermal head base
Inventor: MASATSU HIDEAKI
IPC: C09D177/00
Filed: 1992-05-08
Abstract: PURPOSE:To obtain a protecting film-forming agent for thermal head base, having approximately the same coefficient of thermal expansion as that of thermal head base, not causing warpage, etc., not corroding an element on a base, comprising a polyether amide and an ether-based solvent. CONSTITUTION:A protecting film-forming agent for thermal head base comprises (A) a polyether amide of formula I (X is bifunctional atom or functional group; Ar is aromatic hydrocarbon; Rn is alkyl) and (B) an ether-based solvent of formula II (l and n are 0 or 1 or >1; m is >=2) (e.g. diethylene glycol dimethyl ether) alone or a mixture of the ether-based solvent and an ester-based solvent as essential components. Since the protecting film-forming agent contains the polyether amide resin whose coefficient of linear thermal expansion is close to that of the thermal head base, neither warpage nor undulation of base will occur during rise in temperature and since the solvent of the component B is neutral, the solvent will not corrode an electric part (aluminum, etc.) on a base.

Filed: 1990-05-02
Abstract: PURPOSE:To read an intermediate level of a changing-over numeral visually by a method wherein a displayed numeral changes over with scrolling to a numeral to be displayed subsequently, when a numeric value displayed in each digit is incremented or decremented. CONSTITUTION:When a numeral displayed in dots on a display screen is incremented or decremented, a numeral to be displayed subsequently is displayed in dots with gradual scroll from the former numeral to it, by making it scroll upward by one dot, for instance. When a figure A changes over to C through B, for instance, the dot display change in such a manner that numerals '3' and '0' in the lower two digits rise with scrolling simultaneously with the rise of numerals '2' and '9'. Every time when a running distance increases by 0.01 km, the display rises by one dot, '2,9' disappear gradually and, instead, the next display '3,0' appear. According to this constitution, it is possible to make an observer recognize easily an approximate value of an intermediate numeric value with high precision.

Abstract: PURPOSE:To make it possible to suck heavy dust while effectively using electric power of a power source with small capacity by a method wherein a control device is controlled to increase the supply power to a motor as well as the suction force of a fan by depressing a main body case movable vertically to a cleaning surface. CONSTITUTION:When dust collector (brushes) 27 are contact on a table T and the like, and slid, the dust on the table is sucked from an inlet 20 and held into a dust compartment 23, after a main body case 1 is held by the hand and a motor 7 is started. For heavy dust existing on the table, an operating rod 35 is lifted by the upper surface of a base plate 26 and a switch 36 is turned on when the main body case 1 is lowered as it is. In this case, the heavy dust is sucked by strong suction force since a control device 38 is short-circuited, and the supply power to the motor 7 is increased, and then the rotation speed of a fan 9 is increased. On the other hand, when the passage of the air sucked into the inlet 20 is made smaller by the case 1 being lowered, stronger suction force is obtained since an air flow speed becomes higher.
